More than plane water

Air China is introducing the brand 5100 bottled water to serve passengers in first and business classes to enhance cabin service.

"We're very prudent in choosing a catering partner," said Hu Min, senior manager of Air China's cabin service department. The mineral water finally got a permit after rounds of tests and checks by the carrier to prove its quality and brand value.

5100 water, dubbed China's Evian, bottled in Damxung, about two hours from Lhasa, Tibet, is a famous water brand.
